Title: Broadcom DSL Diagnostics App
Post by: GigabitEthernet on June 12, 2012, 05:43:07 PM
I stumbled across an official Broadcom app for line diagnostics. It lets one run QLN tests etc.

It can be downloaded from here (ftp://ftp.zoomtel.com/pub/DslDiag.zip).

To use it:
1. Open the CMD prompt and "cd" to the extracted folder containing the Broadcom app.
 2. If you are using a NETGEAR router, visit this address (http://192.168.0.1/setup.cgi?todo=dsldiag) in your web browser, otherwise, disregard this step.
3. Type "bcmdsldiagsl -s ROUTERIP.
 
That's it. Have fun!

Well spotted! That looks very interesting, and it works on Linux with Wine too.

Three exe files. I wonder if they are worth disassembling, analysing and re-writing in C, ready for recompilation -- for Linux kernel based systems . . .  ::)

Are you volunteering? :)

There are good disassembling tools in Linux, but the analysing and rewriting parts would be way beyond my (in)competence.

how does one telnet to a folder?

EDIT: Im not telnetting but ive managed to open it from cm prompt but it just says SOCKET CONNECTING and does nothing?

it looks like it might be good too :)

He didn't mean 'telnet'. You CD to the directory where the files are extracted, then type

bcmdsldiagsl -s 192.168.0.1  (or whatever the IP address of your router is)

On a reply to a post I made about the Zoom X7N on Amazon! I was replied to with a link to the Zoom FTP site and I downloaded it.

Can anybody confirm that it works with other routers like the NETGEAR DG834GT, etc?
Title: Re: Broadcom DSL Diagnostics App

It works perfectly with the D-Link DSL-2740B
Title: Re: Broadcom DSL Diagnostics App
Post by: les-70 on June 13, 2012, 08:45:22 AM
 Please can someone say what happens after the application starts.  I also just get a "Socket Connecting....." and nothing else.

 I am using a DG834G v4 with DGTeam but I assume that irrespective of the router and firmware it still needs to login?? Maybe it uses a port disabled with DGteam.  I could try the Netgear firmware or a Dlink 2640b but wondered what should come after "socket connecting".
Title: Re: Broadcom DSL Diagnostics App
Post by: roseway on June 13, 2012, 09:30:28 AM
It shows "Socket connecting" if you start it without specifying the router IP address, or if you give it the wrong address. Are you sure you're entering the IP address of your router correctly?

I really don't know, I'm afraid. Maybe it's a problem with Netgear routers? Or it might be using an anonymous telnet interface which isn't available in the DGTeam firmware. Just speculation...

Just a thought, maybe telnet needs to be manually enabled prior to running the program:-

there is even a DSLDIAG enable link in asbo's link to that website that mentions it , I tried that with no success.. I think its DG Team FW... right... wheres that 834GT amd my flash util!!! hehe

The Broadcom diagnostic client is trying to connect to udp/5100 on the router. On the Huawei HG612, there's nothing listening on that port, so it just hangs with a "Socket Connecting.." message.

just tried with a DG834GT with both DGTeam and Netgear Firmware and still "socket connecting" :(

@ AR545 - what router you having success with?

@ ASBOKID - is there no way of forcing the router to listen on that port (unfamiliar with it myself)

edit: tried creating services on port 5100-5102 on UDP and then allowed them in firewall rules, both ways and results are same :(
edit2: tried adding an ALG Service on UDP port 5100...no joy :(

Zoom X7N. Roseway seems to have success, Roseway, what modem are you using? I didn't have to do any special configuration on my router, it worked out of the box.

I believe they show the noise on a particular tone, you can configure what is shows on one of the menus.

I'l try my DG834GT when I get the chance. I'll also post some more screenshots.

Edit: It does not work with the NETGEAR DG834GT. Screenshots will be added in due course.

I tried that link last night on my 834N with DGteam fw... doesnt work... I guess I will try my 834GT again

the 834N has same chipset as the D-Link 2740B that Eric and Les have it working on...so should work?  perhaps its the DGteam fw..?

ok, working on my DG834GT with Netgear FW... would not work with DGteam firmware (even with dsldiagdebog link) and does not work on my 834N with DGteam..i bet it would work on it with Netgear FW though

i will run some of the tests later as its my spare router... or i may run them on my Speedtouch 585v6 (should work on that?)

I doubt it, the Thomson routers always used/use a custom CLI that I doubt is compatible with this app. I am happy to be proven wrong however :).
Title: Re: Broadcom DSL Diagnostics App
Post by: snadge on June 13, 2012, 10:14:38 PM
I can confirm that you need to use the DLSDIAG DEBUG link on Netgears to get it working...

i dunno what most of this stuff is or what the tests are doing (or if they are even running?) I run a QLN test which completed and graphed out my QLN with a few more graphs overlapping almost exactly the same as the QLN...

it seems to have a bug where it reports the actual sync rate at 4544 / 544 sometimes

anyone find anything of use/new ?  I cant do anything just now as 'pops' is using other PC and the wireless is dropping cos the Netgear wg111t stick is poop

Hmmm, wonder if there is a corresponding URL to enable it on the HG612, as there is plenty of reference in the program to VDSL & VDSL2.

Perhaps asbo may be aware of a URL from his earlier work on unlocking ?

Hi, Blackeagle,

It works fine on the HG612. However, sfaics, there's no hidden URL in the Huawei's web GUI to enable the diagnostic daemon.

So, log in as normal via telnet, and start the daemon (dsldiagd) from the shell:

Code: [Select]
BusyBox v1.9.1 (2010-10-15 17:59:06 CST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

# dsldiagd &
#

Check it's running with:

Code: [Select]
# netstat -lu
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
udp        0      0 0.0.0.0:snmp            0.0.0.0:*                           
udp        0      0 0.0.0.0:domain          0.0.0.0:*                           
udp        0      0 92.26.201.144:1718      0.0.0.0:*                           
udp        0      0 0.0.0.0:bootps          0.0.0.0:*                           
udp        0      0 0.0.0.0:tftp            0.0.0.0:*                           
udp        0      0 0.0.0.0:5098            0.0.0.0:*                           
udp        0      0 0.0.0.0:5099            0.0.0.0:*                           
udp        0      0 0.0.0.0:5100            0.0.0.0:*                           
#

And there at the bottom, listening on 5100/udp is the control socket of dsldiagd, the diagnostic daemon.

That should work for all modems with dsldiagd included in their firmware.

After starting the daemon, the telnet session can be closed.

And as Roseway has noted, the diagnostic client for the client runs okay in Linux using WINE.

(https://forum.kitz.co.uk/proxy.php?request=http%3A%2F%2Fwww1.picturepush.com%2Fphoto%2Fa%2F8494464%2F480%2Farobertson545%2Fbroadcomdiagnostictoolscreenshot.png&hash=b21fa80c555c1bdc779fb55ac33b20b0) (http://picturepush.com/public/8494464)

It looks like the graphs are showing QAM constellation maps for two different tones. The left one (Main Eye display) is for a tone in active service, the right one is for the pilot tone (DMT#64 in this case).

Great find arobertson545!

Title: Re: Broadcom DSL Diagnostics App
Post by: snadge on June 14, 2012, 03:46:48 PM
I dont get any activity in constellation map (eye)

after faffing on with it on my 834GT I had wifi packet loss problems shortly afterwards...probably unrelated but reboots of router and pc would no resolve it.. I will reset and reflash it later and see if that restores it, im using my 834N now

so... can this do anything for us we couldnt do before? 
can these tests help us find problems we couldnt before?

You have to enable it. Under the View menu select Eye Display Configuration. Check the Enable box and click OK.

ahh i see, thanks Eric,

guess we'll have to wait for Asbo (our resident Scientist, hehe) to strip it down and figure it out..

Thanks asbo,  it's working fine now,  which is more than I can say for the M$ box it was running on lol

darn it!!  DLM kicked in with all my reboots/resyncs lol... dropped me to the 16Mb profile with aggressive error correction INP=2 and 384 Interleaving lol - got it put back via sky forum PM... 

anyone sussed out this tool yet?

the dsldiag debug link forces a re-sync just in case your not aware

This is a very significant find by arobertson545.

Just had a brief look with a packet sniffer at the traffic between the Broadcom diagnostic client (BcmDslDiagsL.exe) and the embedded server (dsldiagd) and the protocol doesn't look that complicated (famous last words, perhaps).

If that tickles the fancy of anyone here, maybe we can collaborate on reverse engineering it?

cheers, a

If you remember, I was scratching an itch in Reply #2 (http://forum.kitz.co.uk/index.php/topic,11293.msg218598.html#msg218598).  :P  Eric saw me scratching and he appeared to be interested (http://forum.kitz.co.uk/index.php/topic,11293.msg218612.html#msg218612), being a fellow Penguin Hugger.

After subsequent considerations, I declared (http://forum.kitz.co.uk/index.php/topic,11293.msg218618.html#msg218618) that the efforts of a higher status wizard would be required . . .

Attached is the C header holding the definitions for the network interface for the Broadcom DslDiag diagnostic daemon.

The file came from the source code tarball for the DG834GB v4. [1] The header file is identified as Revision 1.23, dated 2005/07/14, some seven years ago.   Maybe there is a newer version out there?

Hopefully the header still contains enough info to re-create a PC client to obtain additional diagnostic stats from the DSL hardware driver layer.

In the same source tarball, the file DG834GBv4_V5.01.01_src/bcmdrivers/broadcom/char/adsl/bcm96348/BcmAdslDiagLinux.c has more info.

The BCM diagnostic tool - both client and daemon - remain closed source, but here [2] we get a glimpse at the codebase when an embedded developer asks for assistance with building the daemon under Hudson.

Title: Re: Broadcom DSL Diagnostics App
Post by: asbokid on June 29, 2012, 02:26:59 AM
Much credit and thanks to arobertson545 for telling this forum about dsldiagd, the Broadcom diagnostic tool.

A basic DSL diagnostic client has been built in C for the host PC. It can interrogate the DSL diagnostic daemon running on the Broadcom target.  The diagnostic tool uses a diagnostic network interface. That uses the UDP protocol on port 5100.  The diagnostic data from the target is encoded in the UDP datagrams sent by the Broadcom daemon to the PC client.

But first of all, the daemon has to be woken up with some magic datagrams.  Time synchronisation is also involved.   Once initialised, the diagnostic daemon starts to report in a round-robin fashion perhaps fifty different types of line diagnostic data, each with its own 4-, 8- or 12- byte header in the datagram.  Just half a dozen of these headers are understood to date.

Some types of diagnostic data, the line error counters for example, are readily identifiable (see below).   But the most interesting data isn't yet decoded.   Does anyone fancy working on this? It's a reverse engineering exercise. The source code is pretty crude at the moment. To be compatible with BillyGatesWare, tjat limits its design.

It looks like it's possible to get live QLN data using the tool.  That is presumably achieved by disabling during showtime the bit-loading on a tone. That allows the background noise on the subcarrier to be measured.  It would be great to reverse-engineer that specific functionality.   At the moment though, the tool cannot get anything much that the xdslcmd doesn't already provide via the telnet interface.  So nothing to get very excited about!

cheers, a

Not sure I'll do much with it. Without collaboration, it's quite a big job to get it to something functional. However, the code can be uploaded - it's only about 20kB of C source. That might save unnecessary re-inventing of the wheel.

My problems are:

(1) Time deficiency.
(2) Not possessing any equipment that runs BillyGatesWare, with which to execute the original code.  :-X

Perhaps one of the Eagles will be interested?  :-\

I think it should, but just about all the available knowledge on the tool is in this thread. Just guessing, you may need to start the dsldiag demon running in the router, as described by asbokid in relation to the HG612. Alternatively I might be talking nonsense.

Would anyone be willing to captures some traffic in wireshark and send me the pcapng file?

I'd like to see if I can make any sense of the protocol/reverse engineered code but don't have a compatible router at the moment (will probably pickup a cheap one off ebay sometime) - but I can test with an emulator for now.

A really old post but, as I could find anywhere better, I thought I would add some details from experimenting here (I haven't done much, but at least one bit seems new):

Beyond the Eye views, the Status and the State summary there are 6 windows available:

Bit Allocation - Bitloading in a one histogram bar per tone
Gi Allocation (Gain) - The gain applied to each tone.  My guess is in a perfect line this would be a straight line
SNR - Signal to Noise Ratio (contains Minimum and maximum as well as current
Showtime Margin - the Margin for each tone at the point of synchronisation
Channel Response - The HLog
Quiet Line Noise  -  Also shows Minimum and maximum when shown during the QLN Monitoring (from the tests menu)


Title: Re: Broadcom DSL Diagnostics App
Post by: boozy on July 06, 2018, 09:43:32 PM
When I was playing I put the modem into L3 State (idle, no connection)

QLN Monitoring uses the QLN view.  There are 2 parameters, Duration and Frequency (forgot to screenshot so will edit next time I play with it).


The result is the QLN, along with a minimum and maximum over the time you set.  It reverts to the last QLN if you shut the window.
Title: Re: Broadcom DSL Diagnostics App
Post by: boozy on July 06, 2018, 09:52:20 PM
In the AFE tests the two loopback tests fail, likely as they need a strap at the other end.

The Hybrid Response Test runs and produces a HLog Graph (of what I don't know yet :)).  But it definitely relates to the QLN (mine's weird, and so is that HLog).  The QLN is not the usual one - so I'll have to edit this again once I figure how I got it.  The normal QLN is labelled SnrC and this one just QLN.  There's a direct correlation between the peaks and troughs.

I did poke at lots of things, but hadn't thought to screen capture or document what I'd done (which I now wish I had).  There may be more useful info so I'll keep a post for next time I have the modem disconnected.
